simple script to find the number of "tab"s...but,...
------------------------------
$x=" hi";
$tabspace=0;
while ($x =~ /\t/g )
{
$tabspace++;
}
print $tabspace;
---------------------------------

1.)when i tried it without "g" ($x = ~/\t/ )... when i run the script it utilizes around 95% cpu and system hangs and i did "End process" for perl.exe
2). and in the input string instead of using "tab key" i used "space" key "five times"... like "-----hi" ...........think that"-" is a space key.
i thought that five spaces (or four or six...)are equal to one tab...but i got printed 0 tabs....

windows environment...activestate perl...5.6.1

thanks in advance...

XmProcessTraversal(3X)													    XmProcessTraversal(3X)

NAME

       XmProcessTraversal - A function that determines which component receives keyboard events when a widget has the focus

SYNOPSIS

       #include <Xm/Xm.h>

       Boolean XmProcessTraversal (widget, direction)
	       Widget widget;
	       XmTraversalDirection direction;

DESCRIPTION

       XmProcessTraversal determines which component of a hierarchy receives keyboard events when the hierarchy that contains the given widget has
       keyboard focus. Using XmProcessTraversal to traverse to MenuBars, Pulldown MenuPanes, or Popup MenuPanes is not supported.   Specifies  the
       widget ID of the widget whose hierarchy is to be traversed. The hierarchy is only traversed up to the top of the shell.	If that shell does
       not currently have the focus, any changes to the element with focus within that shell will not occur until the next time the shell receives
       focus.  Specifies the direction of traversal

       The direction parameter can have the following values, which cause the routine to take the corresponding actions: XmTRAVERSE_CURRENT--Finds
       the hierarchy and the tab group that contain widget. If this tab group is not the active tab group, makes it the active tab group. If  wid-
       get  is	an  item in the active tab group, makes it the active item. If widget is the active tab group, makes the first traversable item in
       the tab group the active item.  XmTRAVERSE_DOWN--Finds the hierarchy that contains widget. Finds the active item in the	active	tab  group
       and  makes the item below it the active item. If there is no item below, wraps.	XmTRAVERSE_HOME--Finds the hierarchy that contains widget.
       Finds the active item in the active tab	group  and  makes  the	first  traversable  item  in  the  tab	group  the  active  item.   XmTRA-
       VERSE_LEFT--Finds  the  hierarchy  that	contains  widget. Finds the active item in the active tab group and makes the item to the left the
       active item. If there is no item to the left, wraps.  XmTRAVERSE_NEXT--Finds the hierarchy that contains widget. Finds the active  item	in
       the  active tab group and makes the next item in child order the active item.  XmTRAVERSE_NEXT_TAB_GROUP--Finds the hierarchy that contains
       widget. Finds the active tab group (if any) and makes the next tab group the active tab group in the hierarchy.	XmTRAVERSE_PREV--Finds the
       hierarchy  that	contains widget. Finds the active item in the active tab group and makes the previous item in child order the active item.
       XmTRAVERSE_PREV_TAB_GROUP--Finds the hierarchy that contains widget. Finds the active tab group (if any) and makes the previous	tab  group
       the active tab group in the hierarchy.  XmTRAVERSE_RIGHT--Finds the hierarchy that contains widget. Finds the active item in the active tab
       group and makes the item to the right the active item. If there is no item to the right, wraps.	XmTRAVERSE_UP--Finds  the  hierarchy  that
       contains  widget.  Finds  the  active  item in the active tab group and makes the item above it the active item. If there is no item above,
       wraps.

   CAUTIONS
       XmProcessTraversal will not allow traversal to a widget in a different shell.  XmProcessTraversal will only allow traversal to widgets that
       are currently mapped.  You cannot call XmProcessTraversal from inside a focusCallback routine (or you will get a segmentation fault).

RETURN VALUE

       Returns	True if the setting succeeded. Returns False if the keyboard focus policy is not XmEXPLICIT, if there are no traversable items, or
       if the call to the routine has invalid parameters.
